On bearing failures such as roller bearing rings, ribs hurt, as a reason to consider, for oil lubricant inadequate, inappropriate, construction defects, intrusion of foreign bodies, bearing misalignment, shaft deflection is too large, there will be these reasons coincide.
Therefore, only investigated damage, it is difficult to know the real causes of injury. However, if you know the bearing condition of used machinery, used, constructed around the bearings, understanding of the situation before and after the accident, combined with several causes bearing damage and visit, they can prevent similar accidents happening again.
Judgement of bearing:
Judgement of bearing is available, mainly bearing damage, mechanical performance, the importance, the operating conditions, to be determined during the next maintenance. If you have the following defects can no longer be used, new bearings must be replaced. Inner ring, outer ring, rolling elements, cages on any cracks or gaps.
1, rings, rolling elements on any one broken.
2, rolling road surface, the ribs, the rolling of a significant injury.
3, cage wear and dramatically significant relaxation or rivets.
4, rust on the roller surface, rolling, had injuries.
5, roll on the road surface, rolling with serious pressure marks and traces.
6, clear the inner ring diameter or outer ring outside diameter surface creep.
7, because thermal discoloration caused by obvious.
8, into the grease bearings, seals or shields of damage apparent.
